If the module’s Acceleration Redundancy Manager is configured for use then
each module uses its local derived acceleration signal and the shared
acceleration signals from the other two modules to select/vote the signal to use in
its over-acceleration detection logic. Each module’s Acceleration Redundancy
Manager can be configured as follows depending on the number of used or
healthy speed signals:
1. Three used/healthy speed/acceleration signals condition (Base Function):
a. Median signal (middle signal)
b. Highest
signal
c. Lowest
signal
2. Two used/healthy speed/acceleration signals condition (Fallback Function):
a. Highest
signal
b. Lowest
signal
3. One used/healthy speed/acceleration signal condition (Two Inputs Failed
Action):
a. Used/sensed healthy speed/acceleration signal
b. Issue a trip command
Start Logic
The start signal is generated by selecting the START button on the module front
panel or by closing the dedicated Start contact input. The start signal is edge
triggered and re-selecting Start will reset the timer.
The ProTechTPS control’s failed speed signal detection logic is used to sense
no/zero speed and issue a trip command. However, before a prime mover is
started and as its speed gear begins to turn, magnetic speed probes output a
zero rpm signal until the speed exceeds the probe’s minimum frequency. Two
different start logic functions are available to use within the ProTechTPS to
override failed speed signal detection logic and allow the prime mover to be
started. Either, both, or neither of these methods can be selected. There is also
an alarm that can be enabled to indicate any time the Speed is below the Speed
Fail Setpoint.
